List of KitchenAid mixers with brushless DC (BLDC) motors
Brushless DC (BLDC) motors have many advantages over other motor types in terms of durability, noise, efficiency, and consistency. A well-designed induction motor system can be competitive, but for home appliances is usually considered inferior.
BLDC motors/controllers are complex to design and expensive to build so are usually included only in higher-end appliances.
I researched which KA mixers have a BLDC motor because my wife has expressed interest in breadmaking. The following is an exhaustive list of KA's residential mixers with BLDC motors:
- KSM7586P* (currently marketed as the "Pro Line Series 7-Qt Bowl Lift Stand Mixer"
- KSM6573* (currently marketed as "6-Qt. Professional 6000 HD" and sold at Amazon, Costco, and certain other retailers but not directly by KitchenAid). This one has an unusual bowl design making it incompatible with certain KA accessories.
- KSM6521* (currently marketed as "Professional 6500 Design™ Series bowl-lift Stand Mixer").
Note the * is a wildcard for any submodel. For example, KSM6521XCA is a red KSM6521 with a glass bowl.
Several KA employees told me that their commercial mixers (all 1 of them) do not use a BLDC motor, but they also told me that the commercial mixers are handled by another department. The mostly useless KA website implies that the motor is the same as used in the Pro Line series, but this is speculation.
I don't make bread but in my research, I found this site's forums useful so decided to contribute back.
